[0057] Referring to FIGS. 6(a), 6(b), and 6(c), the guard 6 has the
suspension structure 61 for hanging the tool, a quick release
member 62, a main plate 63, and a cushion pad 65. The main board 63
is made by hard material, such as metal or plastic. The main board
63 has a substantially planar inner side and a substantially planar
outer side, the quick release member 62 is fixed to a bottom of the
main board 63, the suspension structure 61 is detachably connected
to the quick release member 62, and the cushion pad 65 is disposed

the tool on the operator.
[0058] FIG. 6(b) is an exploded view of the guard 6, wherein the
quick release member 62 has a first member 621 fixed to the main
plate 63, a second member 627 detachably engaging with the first
member 621 and a third member 626 remain the second member 627 to
the first member 621. A top of the suspension structure 61 is
pivotally assembled to the second member 627.
[0059] The first member 621 has an extension 6210 extending
substantially along the main plate 63 and an end portion 6211
extending outwardly and downwardly from the extension 6210.
Conjoined with FIG. 6(c), the extension 6210 is substantially in a
vertical direction, and an angle between the end portion 6211 and
the extending portion 6210 is an obtuse angle. An upper portion of
the second member 627 substantially extends in a vertical direction
and provided with a through hole 623, the end portion 6211 passes
through the through hole 623 of the second member 627 to connect
the first member 621 with the second member 627. The end portion
6211 defines a stopping hole 622 passing through the through hole
623 to be exposed outside.
[0060] The third member 626 is retained to the first member 621 and
has a tail portion 625 extending downwardly and assembled with a
stopping member 624. The third member 626 is preferably of a
flexible material. After the end portion 6211 of the first member
621 passes through the through hole 623 of the second member 627
and expose the stopping hole 622, the stopping member 624 is
inserted into the stopping hole 622 to block the first member 621
from escaping from the through hole 623, in another words, the
stopping member 624 can prevent the second member 627 with the
suspension structure 61 from falling downwardly from the first
member 621. When an emergency occurs, the tool need to be unloaded,
but cannot be unloaded or can't be loaded in time. At this time,
only needs to pull up the tail portion 625 by hand, and the
stopping member 624 is pulled out from the stopping hole 622, then
the tool, the suspension structure 61 and the second member 627
will fall together under the action of gravity. So that the quick
release member 62 facilitates an escape of the operator in
emergency situations and improve the safety performance of the
entire tool carrier 100.
[0061] In the actual working process, the operator may work on a
slope or have a front-to back movement. Therefore, the guard 6
slides relative to the bearing belt 7 can increase comfort level
for the operator and improve work efficiency. In order to realize
the sliding connection between the bearing belt 7 and the guard 6,
the guard 6 in a first embodiment is as follows:
[0062] A sliding structure 66 is fixed to a top portion of the
guard 6 by riveting, welding, etc., and is provided with a sliding
hole 64 through which the bearing belt 7 passes. The sliding
structure 66 is a metal component or a plastic component, and can
be integrally formed with the first member 621 or be assembled to
the main board 63 as a separated component. In this embodiment, the
sliding structure 66 has a piece-shaped structure, which is not
disposed in parallel with a main plane of the main board 63 but
twisted relative to the main plane of the main board 63.
[0063] Conjoined with FIG. 6(d), a top of the sliding structure 66
is disposed at an angle a with the main plane of the main board 63,
wherein the angle a is an acute angle, which is specifically
0-90.degree., preferably 0-60.degree., and more preferably
25.degree.-35.degree., wherein when the sliding structure 66 is
disposed perpendicular to the main board 63, the angle a is about
90.degree.. That is, the above-described angle a is formed between
a horizontal projection of the sliding hole 64 and a horizontal
projection of the main plane of the main board 63. Actually, the
main plane of the main board 63 substantially in the font-to-back
direction, so the sliding hole 64 is set at an angle relative to
the font-to-back direction. The bearing belt 7 passes through the
sliding hole 64 and form a bending line as engaging with the
sliding hole 64, the bending line extending along a direction with
an acute angle to the front to back direction as observed from a
top side. So that the bearing belt 7 can slide along the
font-to-back direction. The elastic band 10 connects the top of the
sliding structure 66 to the guard 6 to disperse the weight of the
tool hung on the suspension structure 61. In order to increase the
aesthetics of the overall structure of the guard 6 and improve the
safety performance, an outer case (not shown) may be provided
outside the sliding structure 66, and the outer case (not shown) is
fixedly coupled to the main board 63 and an opening is provided at
a top of the outer case for the bearing belt 7 to pass
therethrough.
[0064] FIG. 7(a) and FIG. 7(b) show another guard in a second
embodiment, the difference of the guard in the second embodiment
with the guard in the first embodiment is a different sliding
structure, other structures are substantially same. The sliding
structure in the second embodiment is a support member 681 fixedly
mounted on the upper portion of the guard 6, the support member 681
has a U-shape with a U-shaped groove, a rotating shaft 682 passes
through a pulley 68 and inserts two holes defined on two opposite
sidewalls of the U-shaped groove to pivotally assemble the pulley
68 within the U-shaped groove. The bearing belt 7 passes through a
gap between the pulley 68 and the bottom wall of the support member
681. The gap can be regarded as a sliding hole defined in a plane
which is perpendicular to the front-rear direction and running
through along the front-rear direction, so that the guard 6 is
slidable along the bearing belt 7 along the front-rear direction.
Similar as the guard in the first embodiment, the top of the guard
6 connects with the waist belt 5 by the elastic band 10 to disperse
the weight of the tool hung on the suspension structure 61. The
tool can drive the guard 6 to slide along the bearing belt 7 in the
front-rear direction, which improves the working comfort of the
tool carrier 100.
[0065] FIG. 8(a) and FIG. 8(b) shows another guard in a third
embodiment, wherein the suspension structure 61 and the quick
release member 62 are omitted for simple description. The
